Title: Process and apparatus for spreading liquid or pasty substances
IPC: B05C1/08
Filed: 1958-07-29
Abstract: A liquid or pasty substance, e.g. an adhesive, is continuously or intermittently applied to a support by continuously applying it in a predetermined thickness to the surface of an application roller or the like, substantially completely removing any excess of the coating substance remaining on the roller after the substance has been transferred to the support, by means of a removal device, from which such excess is passed to a storage vessel from which it can be re-fed to the application member.  As shown, the feed and removal devices may constitute a single unit 19 which rests on the application roller 18.  The feed device comprises a chamber 33, filled with the coating material <PICT:0860355/III/1> <PICT:0860355/III/2> <PICT:0860355/III/3> which emerges through slots 38 as a series of stripes 40 on the roller 18.  The removal device is formed by the chamber 34, which excess material 401 enters through a tapered aperture 39. The chambers 33, 34 are connected to a storage vessel 22 by flexible pipes 20, 21 and the pressure generated in the chamber 34 by the rotation of the roller 18, which is driven from a shaft 44, may be sufficient to overcome the hydrostatic pressure of the material in the container 22, and effect circulation.  If necessary, pumping devices may be inserted in the pipes 20, 21. As shown in Fig. 8, the bracket 46 carrying the coating device may be capable of being raised while the roller 18 continues to be driven, so that it is freed from coating-material when not in use. As applied to a labelling-machine, Fig. 9, supports 1 are fed in succession by an intermittently-operated suction-drum 3 and are then forwarded by two pairs of carrier tapes 6, which grip their edges.  The drum 3 is caused to rotate to feed a further support as a previous one contacts a control element 12.  As each support reaches a control element 13, a roller 24 is caused to swing upwardly, pressing the support into contact with the roller 18 to coat the support with adhesive for a length determined by a control-member in the box 16.  As the support reaches the control element 14 an air valve is operated, and a label from a stack 28 is gripped by a suction drum 25, which then rotates through 180 degrees.  When the leading edge of the support reaches the control element 15, a roller 241 is swung upwardly to press the coated portion of the support against the label.

Title: Improvements in or relating to voice frequency signal receivers
IPC: H04Q1/453
Filed: 1958-08-01
Abstract: 831,713. Voice immunity circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 1, 1958 [Aug. 6, 1957], No. 24845/58. Addition to 704,922. Class 40 (4). A signal of predetermined frequency incoming to a V.F. receiver is symmetrically voltage limited to generate the third harmonic which is applied to a circuit tuned to this harmonic over an amplifier having a symmetrical voltage limiter in a negative feed-back circuit so as to provide a threshold for signals applied to the tuned circuit. With a signal frequency of 2280 c.p.s. there is a rick that a voice frequency of 1368 c.p.s. will interfere with its fifth harmonic which coincides with the third harmonic of 2280 c.p.s. The relative amplitude of each of these harmonics produced by symmetrical voltage limiting to a small value E is 4E/3# to 4E/5# so that if the threshold of the negative feed-back amplifier lies between these limits the fifth harmonic will be suppressed. As shown in the Figure the input signal over T1, amplifier V1, and T2, is limited symmetrically by diodes W1, W2, tied to the ends of resistors R4, R5. The third harmonic of the input signal is extracted by the Œ60 c.p.s. band-pass filter F1 and applied to amplifier V2 in the cathode circuit of which is the non-linear impedance presented by transformer T4 and the voltage limiting diodes W3, W4, in its secondary circuit. The cathode circuit of V2 is tuned to a frequency between the fundamental and third harmonic and the anode circuit is tuned to the third harmonic and is connected to energize relay S. When the input to V2 reaches a critical value, diodes W3, W4, conduct and drop the cathode impedance of V2 to R11 to excite the anode circuit. The limiting voltages connected to W3 and W4 are the same as are connected to W1 and W2 which it is shown makes the threshold voltage dependent solely on the turns ratio of T4. It still remains possible for an input signal departing slightly in frequency from the control signal but of sufficiently large amplitude to negotiate filter F1 to operate relay S. To avoid this a backbiased rectifier W7 is forwardly biased to conduct over capacitor C7 whenever an abnormally large signal appears from T2. A voltage from R15 is then smoothed and applied as back bias to V2 to block the signal. An additional untuned transformer may be connected serially with T2 to provide a speech channel.
